To all whom it may concern:

PURsLow, a citizen of the United States,residing at Duran go, in the county of La Plata and State of Colorado,have invented certain new and useful Improvements in Oar-Coupling Links,of which the following is a specification, reference being had thereinto the accompanying drawings.

My invention relates to car-coupling links, the construction of whichwill be hereinafter fully set forth, and pointed out in the claims.

A is the coupling-link,formed in the ordinary manner. Secured centrallybetween the bars is the plate B, having a slot, b, as shown. The slot isrectangular in outline, and is adapted to receive key D. I

D is the link-key. Its lower portion has projections d, the upper edgesof which are beveled inwardly, as shown. The shank of the key, where itpasses through the plate B, is formed with notches d, which allow thekey to turn freely. The key is also formed with a 7 suitable handle, 61

In operation the lower end of the key is in- 0 sorted through the slotin the plate B, and when the projections 01 have passed through and areon the under side of the plate the key is turned in the slot, the angledprojections d extend upwardly above the bottom of the plate 3 5 andprevent the key from turning back and slipping out of the slot.
